Apparatus for applying liquids



Feb. 9 1926.

F. M. FURBER APPARATUS FOR APPLYING mourns Filed Sept. 1923 the casing. About the plug, opposite the opening El, is an annular groove til-l, which is oi? such width loiigitudinally of the plug that. it will remain always in communication with the air(.ipeni11g il-l however the plug maybe adjusted along the pas age 255. into the groove 23-iopcns a transverse passage {to through the plug, and connected to the passage tilt is an axial longitudinal. passage 38, the latter extending through a reduced tip All upon the luul y-} mition ot the plug, furnishing an air-dischargeuiozzle, the openingot which lies opposite the liquid; opening Q6. The threads of the passage 2:3 and the plug 32 extend both above and below t to aicopening 2 1; and groove 34, and mane tain a tight closure against the passage ot air between the plug and casing in both directions alter it has been i d through the opening til, contining this to delivery through the nozzle *it). ttince the threaded portions are o'ti equal diameter thwugho ut, and are formed upon each of the respective eltui'ient's by a single operation, the integrity oi? the joints will be maintained however the plug .32 may be turned in its adjratmcnt along the passage. This adjustn'ient may be etl'ected by a head or lingenpiece t8, the positioned plug bcingrhcld by a nut 50 operating upon the portion ot the plug rislug above the casing and contacting with the portion it} the casing.

Into the lower end of the passage 22 is threaded a bushing lit, located axially of which a jet-opening ll; alined with the longitudinal passage oi? the plug. lhis bushing is remo *able, to be replaced by another when the opening it. becomes worn, the change being etlected by turning the bushing by engagemtuitwith a squared portion -lti at its lower end. Through this replacement, the diameter oi? the jet-opening may be kept substantially constant. Further, by turning the bushing in the threaded passage 22, it may be caused to move up or down therein, thus changing its relation to the liquidopening 9.6 and to the nozzle it), it being "held against displacement by the frictional engagement of the threads. It will be ob served that in this adjustment the upper end of the bushing moves across the edge ot' the litpiitbopening 26, thus varying the area of the latter.

To state briefly the well-known action of the organization. air under pressure, forced through the conduit 10, flows by way of the opening it, passages so and 38 and nozzle all), into a chamber iii, in which the nozzle is situatethand is discharged through the jet-opening ti. By its how, it produces a partial vacuum in the chamber ati', which causes atmospheric pressure upon the liquid in the receptacle 3b, to torce this liquid up the conduit 23 and through the opening 2e into the chamber ti". Here, meeting the air from the nozzle, it is atomized, and thrown "from the jet-opcning as a spray, The rate at which the liquid is drawn through the conduit depends upon the area of the opening :lt' where it communicates with the ehmnbcr all, the height olfthe upper end o t the jet-opening -l-t above the liquid in the receptacle, and the degree of the vacuum pro duced in the chamber it The [inencss oi? the spray ejected through the jet-opening varies with the distance between the lower extremity o t the nozzle ll) and. the upper end ot the opening H. The imglcpeudent adjustment of the plug 3:3 and the bushing gives a. capacity tor altering particular relations between the elements without disturbing other rclatiom; which may have been established. in this way, there is assured it very exact control of the quantity and character ot the spray discharged, to best meet varyingconditions in the character of the stock treated, ot the stain applied, and in the depth of color to be imparted.

llaring descrilaal my invention, what'- I claim as new and desire to secure by 'l'ietters .l 'atent, ot the United States is 1. In an apparatus of the class described, a casing having a jetopening and a liquid inlet-opening, an air-nozzle delivering to the jet-opening, and means arranged to permit the relation ot the jet-opening tothe airnozzle and to the liuuid-inlet-opening to beh varied.

52. In an ap ntratus ot the class described,

a casing having a jct-openin, and a liquidinlet'opcning, an air-nozzle variable with respect to the .llqtttEl-1l1lCt-O])Bl1l11g, and means arranged to vary the relationot the jet-' opening to the liquid-inleoopenin V.

:3. In an apparatus of the class described, a casing having a liquiddnlet-opening, an air-nozzle associated with the casing, and a member containing a jet-opening .co-operattag with the liuuidopening and air nozzle and being separably mounted in the casing.

at. In an apparatus of the class described,

a casinghaving a liquid-inlet-opening, an-

air-nozzlc associated with. the casing, and a member containing a jet-opening and being.

mounted in the casing to move into different relations to the liquid-opening and air-nozzle.

5.1a a blaclung apparatus,a casing through which is a passage having a liquid-'1 opening communicating with it, an air nozzle co-operating with the passage, and a member containing a jetopening, said member being movable in the passage to vary the elt'ect-ive area oi" the liquid-opening.

(3.111 a blackiug apmratus, a casing.

through which a tln'caded passage having a liquid-opening communicating with it, a threaded plug arranged tor movement along the casing-passage and containing an airpassage, and a bushing threaded to engage the extremit of the casing-passage adjacent to the liquic -opening.

7. In a blacking apparatus, a casing through which is athreaded passage having a liquid-opening and an air-opening conia casing provided with a jetopening, a

liquid-conduit connected to the casing, an air-conduit delivering to the casing, and a nozzle having a body-portion, in which is a passage communicating with the air-conduit and terminating in proximity to the jet-opening, said bodyportion having threaded engagement with the casing at opposite sides of its point of communication with the air-conduit.

9. In an apparatus of the class described, a casing provided with a jet-opening and a passage extending through the casing in alinment with the jet-opening, there being a liquidopening in the passage adjacent to the jet-opening and an air-opening in the passage at a point removed from the jet opening, and a plug provided with apassage connecting the air-opening and jet-opening and having threaded engagement with the casing for substantially its entire length therein at opposite sides of the point of communication between its passage and the airopening.

In testimony whereof I have signed my name to this specification.
